Characteristics of PV generator MPPT
configuration
Notes
The photovoltaic generator is made
up of strings with
differing series
modules numbers.
MPPT
configuration
has to be
INDEPENDENT
A NECESSARY condition for the two MPPT to
be used independently is that the photovoltaic
generator connected to each of the inputs has
a
lower power than the power limit of the single
input channel AND a maximum current lower
than the current limit of the single input channel.
The photovoltaic generator is made
up of strings which have installation
conditions which are
different to
each other.
The photovoltaic generator is made
up of strings with
identical series
modules numbers.
Possibility
of choosing
between the
configuration
with
INDEPENDENT
MPPT or
PARALLEL
A NECESSARY condition for the two MPPT to
be used independently is that the photovoltaic
generator connected to each of the inputs has
a
lower power than the power limit of the single
input channel AND a maximum current lower
than the current limit of the single input channel.
An
ADVISABLE condition (*) in order that the two
MPPT may be parallel, is that the photovoltaic
generator connected to the two inputs is made
up of strings created from the
same number of
modules in series and that all the modules have
the
same installation conditions.
The photovoltaic generator is made
up of strings which have the
same
installation conditions, that is, all the
strings have the
same inclination
angle in relation to the horizontal
plane and the
same orientation to
SOUTH.
The photovoltaic generator connected
to each of the inputs has a
lower
power than the power limit of the
single input channel
AND a maximum
current lower than the current limit of
the single input channel.
(*) The condition is advisable from a system energy production viewpoint, not from the point of view of the
operation of the inverter.
The photovoltaic generator is made
up of strings with
identical series
modules numbers.
MPPT
configuration
PARALLEL
mandatory
A SUFFICIENT condition (*) for the two MPPT
to be used in parallel is that the photovoltaic
generator connected to each of the inputs has a
higher power than the power limit of the single
input channel OR a maximum current greater
than the current limit of the single input channel.
An
ADVISABLE condition (**) in order that the
two MPPT may be parallel, is that the photovoltaic
generator connected to the two inputs is made
up of strings created from the same number of
modules in series and that all the modules have
the same installation conditions.
The photovoltaic generator is made
up of strings which have the
same
installation conditions, that is, all the
strings have the
same inclination
angle in relation to the horizontal
plane and the
same orientation to
SOUTH.
The photovoltaic generator connected
to each of the inputs has a
greater
power than the power limit of the
single input channel
OR a maximum
current greater than the current limit
of the single input channel.
(*) The condition is sufficient from a system energy production viewpoint, not from the point of view of
operation
of the inverter.
(**) The condition is advisable from a system energy production viewpoint, not from the point of view of operation
of the inverter.
